CDM Smith delivered a targeted biosolids sampling and analysis program to support classification under Queensland's Biosolids End of Waste Code. Drawing on expertise in wastewater, contaminated land, and environmental risk assessment, we worked closely with laboratories to achieve required detection limits. Detailed planning, logistics management, and a robust sampling methodology enabled safe, efficient project delivery in a remote location.
CDM Smith's experience with the Biosolids End of Waste Code, combined with careful planning and strong laboratory coordination, ensured samples achieved required pathogen detection levels, giving Council confidence in biosolids classification and future management decisions.
Detailed investigations assessed contaminants, nutrients, microbiological parameters, and physical characteristics to support biosolids reuse, treatment, and disposal planning. The findings informed sustainable management options while reducing environmental and operational risks.

Environmental risk assessment principles were applied to evaluate contaminant pathways, exposure mechanisms, and potential impacts on people, ecosystems, and surrounding land uses. The results supported evidence-based planning, approvals, and long-term operational strategies.
Working in remote South-West Queensland, CDM Smith carefully managed logistics, laboratory coordination, worker safety, transport, and project scheduling. Awarded on Friday and mobilised by Monday, the team safely met Council's timeline and project objectives.
CDM Smith supported Bulloo Shire Council's proposed wastewater treatment plant redevelopment through a biosolids assessment and classification program designed to inform future infrastructure planning and environmental management. The project included targeted sampling and laboratory analysis of biosolids to evaluate nutrients, metalloids, pathogens, and parameters required under Queensland's Biosolids End of Waste Code. A key outcome was providing Council with a clear understanding of biosolids’ quality, environmental risks, and potential pathways for future reuse, treatment, or disposal.
CDM Smith combined expertise in wastewater engineering, contaminated land, and environmental risk assessment to deliver a scientifically robust investigation that considered contaminant pathways, environmental receptors, and long-term operational requirements. Given Thargomindah's remote location, detailed logistics planning and close coordination with analytical laboratories were critical to achieving the required detection limits and project schedule. The program provided an evidence-based foundation for future investment decisions, regulatory approvals, and sustainable biosolids management while helping the Council navigate evolving environmental requirements.
